Synthesis and Characterisation of TiO2/ZnO2 hybrid nanostructures formed by electrodeposition with different Zn(NO3)2 concentrations and used in photoelectrochemical applications [Dataset]

Abstract

The dataset contains the data that have been obtained during the synthesis and the characterization (structural, compositional, and electrochemical) of TiO2/ZnO2 hybrid nanostructures used in photoelectrochemical applications. TiO2/ZnO hybrid nanostructures were synthetized by electrochemical anodization of titanium to form TiO2 nanosponges with crystalline structure and subsequently ZnO electrodeposition. Different Zn(NO3)2 concentrations were used for electrodeposition (10–60 mM). A structural and compositional characterisation was performed using X-Ray Diffraction (XRD). Electrochemical characterisation of nanostructures was performed by Photoelectrochemical Water Splitting (PWS), stability to photocorrosion, Electrochemical Impedance Spectroscopy (EIS), and Mott-Schottky tests.
